Encompassing nearly 5,000 square feet of refined interior space and complemented by more than 3,600 square feet of wraparound terraces, this rare residence offers the scale and privacy of a waterfront estate paired with the convenience and security of one of Longboat Key’s most prestigious condominium communities. From sunrise over Sarasota Bay to spectacular sunsets melting into the Gulf of Mexico, panoramic water views create a breathtaking backdrop from nearly every room. Arrive via a private elevator that opens directly into your own grand foyer, where ornate wrought-iron double doors reveal a residence defined by architectural elegance and meticulous craftsmanship.

At the heart of the residence, the impressive 34-by-41-foot living room is framed by Gulf views and surrounded by multiple entertaining spaces, including formal and informal dining areas designed for both intimate gatherings and grand-scale events. The gourmet chef’s kitchen is beautifully appointed with custom designer cabinetry, stone countertops, decorative appliance panels, a Wolf induction cooktop, oversized island, walk-in pantry, and generous workspace for effortless entertaining. Occupying its own private wing, the primary suite is a sanctuary. A private vestibule leads to a spacious lounge area, dual walk-in closets, and spa-inspired his-and-her bathrooms featuring custom vanities, stone finishes, soaking tub, separate shower, and abundant storage. Floor-to-ceiling glass opens directly to the terrace, where sweeping Gulf views create an ever-changing panorama. Two additional guest suites offer en-suite baths and walk-in closets, while a fourth bedroom—currently configured as a charming bunkroom—provides flexibility for family and guests. A spacious study can easily serve as a fifth sleeping area or executive home office. The outdoor living experience is simply unmatched. Expansive terraces wrap around the residence, creating multiple venues for dining, entertaining, and relaxation while capturing unobstructed views stretching from the Gulf shoreline across Sarasota Bay, the Longboat Key Club golf courses, and the downtown Sarasota skyline.
